Thanks Graydon for introducing me to <xsl:next-match/>, I'm sure it will
be useful. Ken, you are correct, the first fix left my insertion outside
of the <fo:table-cell>, making it ineffective. (I'm inserting
<fo:marker>s to accomplish table title continuation text, which I didn't
mention before.)
So this worked beautifully, thanks Ken:
<xsl:if test="not(preceding-sibling::entry) and
not(../preceding-sibling::row) and
../parent::tbody">
<fo:block> insert FO markers </fo:block>
</xsl:if>
Ken, it's probably because you are an XSL-FO hound and realized what I
was doing!

I have an XML table like below from which I am constructing a roughly
matching XSL-FO table, and I need to insert something extra only in
the first cell of the first row, as indicated:
<table>
<title>My title</title>
<tgroup cols="3">
<colspec colname="C1" />
<colspec colname="C2" />
<colspec colname="C3" />
<thead>
<row>
<entry> text </entry>
<entry> text </entry>
<entry> text </entry>
</row>
</thead>
<tbody>
<row>
<entry> <!-- insert something extra here only --> text
</entry>
<entry> text </entry>
<entry> text </entry>
</row>
<row>
<entry> text </entry>
<entry> text </entry>
<entry> text </entry>
</row>
</tbody>
</tgroup>
</table>
There are templates matching each element: table, tbody, row, entry,
etc. In the <entry> template, how might I check if the current entry
is the first one in the first row? Or is there a better way?
<xsl:template match="entry">
<xsl:if test="MAGICAL XPATH that tells if it's the first cell in
the first row">
<fo:block> insert special things </fo:block>
</xsl:if>
<fo:block xsl:use-attribute-sets="entry">
...
</fo:block>
</xsl:template>
Graydon's answer is good, but my guess is that you are missing in the
template above the <fo:table-cell> in the match for entry. If so,
then the block created by Graydon would end up outside of the table cell.
If you inadvertently did leave it out, then I might use something like:
<xsl:template match="entry">
<fo:table-cell>
<xsl:if test="not(preceding-sibling::entry) and
not(../preceding-sibling::row) and
../parent::tbody">
<fo:block> insert special things </fo:block>
</xsl:if>
<fo:block xsl:use-attribute-sets="entry">
...
</fo:block>
</fo:table-cell>
</xsl:template>
(because of tables inside of tables I didn't use the ancestor:: axis
above)
Axis walking is usually pretty quick. A key table could also be used,
but I'm not convinced it would be any faster since it involves getting
built in the first place:
<xsl:key match="tbody/row[1]/entry[1]" use="generate-id(.)"
name="firstCells"/>
<xsl:template match="entry">
<fo:table-cell>
<xsl:if test="key('firstCells',generate-id(.))">
<fo:block> insert special things </fo:block>
</xsl:if>
<fo:block xsl:use-attribute-sets="entry">
...
</fo:block>
</fo:table-cell>
</xsl:template>
I hope this is helpful.
